Be it known that 1, CHARLES H. AsBURY, a citizen ofthe United States, residing at Post Falls, in the county of Kootenai and State of Idaho, have invented certain new and useful Improvements in W hiftletrees, of which the following is a specification This invention relates to means for attaching clevises to whiiiletrees and has for its object to provide simple, inexpensive and efiicient means whereby the wear upon the whiflletree will be minimized and accidental detachment or. release of the clevis will be prevented. The invention is intended more particularly for use in connection with or bolts were very apt to work loose and ride up out of the said openings so thatthe clevises were accidentally released. Moreover, the strain applied to the whiffietrees was received directly by the wooden body of thesame and the opening "formed therethrough was enlarged so that the whiffietree was weakened and frequently split.

theseobjections areovercomeby the use of.

All

my invention whichis illustrated inthe accompanying drawings and which will be hereinafter fully set-forth.

' Tnthe drawings:

Figure 1 is a perspective view of a whifiietree equipped with my invention;

Fig. 2 is an enlarged perspective view showing the parts separatedbut approximately in theirproper relative positions;

Fig. 3 isan enlarged transverse section of the whililetree showing my, improvement in position thereon. r 3

The whifl'letree 1 is of the usual dimensions and is equipped with an opening 2 near each end, and preferably nearer" the rear side,

and withja similar opening at the center and,

nearer the front side, the openings 'at the ends of the whiflietree being provided to permit the attachment of clevises for supporting swingletrees and the central opening being intended to permit the atttachment of a clevis for connecting the whiiiletree to a plow clevis or to a connecting ring or hook on a harrow'or other farm implement. The central opening also provides for the attachment of the whifl letree to a draft pole Specification of Letters Patent.

or tongue, but in such use the central clevis is not employed. In carrying out my inventiornl employ a bracket or housing consisting of a vertically disposed web 3 having horizontal webs or flanges 4 extending from its upper and lower edges, the web 3 being adapted to fit closely against the front or rear side of the whiiiletree and the flanges 4 being adapted to fit against the top and bottom of the whiffletree, as shown clearlyin Fig.3. At the side edges of the top flange l, I provide the upstanding lugs or side plates 5 and through the flanges 1 T form openings 6 which are adapted to register with the openings 2 in the whifiietree. One of the side plates 5 is provided with a circular opening 7 therethrough and the other side plate 5is provided with a horizontal slot 8 which is disposed at the same distance from the top edge of the plate as the opening 7 and with one end 'alined with the said opening. A retaining bolt or pin 9 is provided and the said pin or'bolt is constructed with an ellipticalhead 10 which is, so formed as to present a slot 11 therethrough. I also employ a key 12 which may be conveniently formed by bending the end portions of a stout wire at right angles to-the main portion thereof, as shown at'13- and 14L,the arms thus produced beingof difierent lengths and the shortcrarm being adapted to pass through the slots 11 and'8 as'will be presently set forth. The'clevis 15 is of any desired or well-known form and isprovided 'at its ends with eyes 16 which are adapted to register with the openings, 6 and 2 as is obvious. v

In assembling the parts, the bracket or housingis fitted tothe whiflietree, as shown in Figs. 1 and 3, so that the .verticalweb and the flanges 4 snugly engage the'top and brackets at the ends of the whiflietree are disposed so that their vertical webs will bear against the rear side thereof. while the. bracket at the center of the whiiiietreebe'ars v3 will fit against the side of the whi'liletree bottom thereof, it being understoodthat the I I 'ed lower eye of'the clevis. It is intended that the whiffiet'ree and-thebracket be of such vertical dimensions that the clevis will fit more or less snugly'thereon but if the distance between the arms of the clevis should be greater than the thickness of the bracket and the whilfietree, washers or liners may be, inserted as is obvious. The elliptical head 10 of the retaining pin orbolt9 is to be disposed substantially parallel with the side plates 5 of the bracket after which the shortarm 13 of the locking key is inserted through the opening 7 and the key turned so. as to bring the'maj or portion thereof into'engagement with said opening and dispose the said arm in" the plane of the slot 8, after which the key is pushed endwisebodily through the slot "11 in th'e head of the retaining pin or bolt and then through the slot 8; .The keyiis then turnedso that its arms 18 and 1 1- will be disposed at right angles to the slot 8 and be'ar against the outer surfaces of the side plates 5, as shown in Fig; 1. Endwisemovement of the keywill be therefore prevented (and, of. course, vertical movementof the memberf 9j cannot occur inasmuch as it is held down to the clevis by the key as will be" readily understood on referenceto Figs. 1 l and 3 of the drawing. 3'0

jflt will be readily understood from the foregoing description, taken in connectionwith the accompanying drawings, that I have produced a very simple device by which the clevis will be securely held to thewhiilletree and accidental releasefofthe restraining and the vertical web of the'bra'c'ket will be whiflletree so that the latter will be effectually bracedagains't breaking or splitting strain. As now ordinarily providedfthe with'the clevis is intended to hold the pin in 7 place but the vibration of the swingletree" 1 Carried by the clevis causes the pintoturn.
